METALLIC WINDOW FRAM' E AND SASH.

SPECIFICATION forming part of Letters Patent No. 714,254, dated November1902. Application filed May 19, 1902. Serial No. 107,939. (No model.)

Be itknown that I, HERBERT A. STREETER, a citizen of the United States,residing in Ohicagopin the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Metallic Window Frames andon1ine77of Fig. 6.

Sash, of which the following is a specification.

My invention relates to improvements in metallic windows, and moreparticularly to the construction of the window frame and sash.

The object of my invention is to provide a. fireproof window frame andsash of a simple, efficient, strong, durable, and economicalconstruction.

My invention consists in the novel construction of parts and devices andthe novel combination of parts and devices herein shown or described.

In the accompanying drawings, forming a part of this specification,Figure 1 is a front elevation of a window embodying my invention. Fig. 2is a horizontal cross-section on line 2 2 of Fig. 1. Fig. 3 is avertical section on line 33 of Fig. 1. Fig. 4 is an enlarged sectionsimilar toFig. 3, but showing the window open, the lower sash beingraised and the upper one lowered. Fig. 5 is a detail vertical section online 5 5 of Fig.3. Fig. 6 is a detail vertical section through one ofthe sash on line 6 6 of Fig. 1. Fig. 7 is a detail section Fig. 8 is adetail top view showing one corner of one of the sash. Fig. 9 is asection on line 9 9 of Fig. 8. Fig. 10 is a sectional view showing amodified construction of the window-frame.

In the drawings like letters of reference indicate like parts in all thefigures.

In said drawings, A represents the wall of the building.

B B are upright steelchannel-bars forming the sides of the metallicwindow-frame, and.

B" B are upper and lower channel-bars forming the top and bottom of thewindow-frame and against which the ends of the side framebars B B abutand to which the same are firmly secured by angle-plates B fitting in 1the angles formed by theprojecting ends Bi of the horizontal frame-barsB B Rivets b areinserted through the angle-plates and theframe-bars, aswill be readily understood from Fig. 5. The projecting ends B alsogroove or channel I) of the channel-bars also affords anchorage betweenthe window-frame and the wall of the building, and being filled in withmortar forms a perfectly tight joint between the window-frame and thewall of the building, free from cracks and crevices, as the metallicwindow-frame will not shrink or warp.

The side frame-bars B B are furnished on their inner faces with guiderails or ribs Z1 the same being removably secured to the frame-bars byscrews b although one of the marginal guide-rails b may, if desired, beformed integral with the side bars, as the sash-frames can be insertedif only two of the guide-rails are removable. The upper horizontalframe-bar B is also furnished on its inner face with similar orcorresponding guide-rails 11 all of which may, if desired, be formedintegral with the upper channelbar 13. The lower horizontal window-framebar 13 is furnished with a single guide rib or rail (9 on its inneredge, as the other guiderails are not required on this lower framebar Band their presence would form channels in the upper surface of the lowerbar for collection of water and dust.

The upper and lower window-sash D D have each vertical rolled-steel sidebars cl d and horizontal bars cl d, the side and horizontal bars beingeach furnished with integral flanges d on their inner faces for thepanes of glass 0 to fit against. The side and horizontal barsd cl arefirmly and rigidly secured together at the corners thereof by projectingtongues d on the ends of the side bars which extend through suitableopenings 01 in the horizontal bar 01 and which are upset or riveted, aswill be readily understood from Figs. 8 and 9. Each of the sash D D isalso furnished with one or more divisionrails d having flanges d d toreceive and i supportthe glass and provided with tongues d? at theirends which project through suitableopenings d in the sash-frame bars dand which are upset or riveted to secure the division-rails in place.

E represents the putty for securing the glass panes C in place on thesash-frames. The upperframe-bar cl of the lower sash D is furnished witha stop-plate F on its upper face the outer edge of which overlaps theprojecting web d of the lower bar d of the upper sash D when the windowsare closed, as illustrated in Fig. 3, thus preventing any crevice oropening between the horizontal frame-bars of the two sash when thewindow is closed. This stop-plate F also underlaps and engages thecorresponding projecting web d of the upper horizontal bar d of theupper sash when the Windows are open, as illustrated in Fig. 4, and thuspreventing the sash from passing each other.

G G are sash-pulleys inclosed in suitable metallic boxes or cases G,resting upon the upper window-frame bar B and in or upon which the shaftg of the pulley is journaled. H is a sash-line, preferably a cord orchain, passing over the sash-pulley and having its ends secured to thesash D D through the connecting eyes h, which are attached to theupright bars (1 of the sash-frame by screws h. The pulley G is mountedcentrally above the sash and equals in diameter the distance between thepoints of connection of the two ends of the sash-line with the sash D D.The sashline H extends through suitable holes oropenings d d in theupper horizontal frame pieces of the sash, these openings or points ofconnectionsof the sash-line with the sash being each located in thevertical plane of the center of gravity of each sash, so that the sashmay slide freely up and down in the sashguideways 17 formed on the sashby the guide rails or ribs 12 Each of the sash-pulleys G is locateddirectly above the upper ends of the side bars B B of the window-frame,so that the sashlines H H fit centrally in the sashways 12 formed by theguide rails or ribs b 19 The sash-pulleys are mounted transversely ofthe plane of the sashthat is to say, their axes or shafts extendparallel to the planes of the sash. In this way one sash balances theother, and sash-weights as well as boxes or ways for the sash-weightsare dispensed with, and the necessity for duplicating the sash-pulleysis also avoided.

In the modification illustrated in Fig. 10 the sash-frame instead ofbeing composed of channel-bars is made of a pair of angle-bars P P,riveted to a connecting flat bar P, which together form, in effect, achannel-bar.

I claim- 1. The combination in a window of a pair of uprightwindow-frame channel-bars B B, horizontal window-frame channel-bars B Bhaving ends B projecting beyond said up right bars and secured theretoby angle-plates B said upright channel-bars being furnished on theirinner faces with guide ribs or rails b forming ways b for the sash, apair of metal sash D D each having upright metal side bars d d andhorizontal bars d d furnished on their inner faces with integral flanges(Z for the panes of glass to fit against and secured together at theircorners by interfitting tongues d and openings 61 the lower sashbeingprovided with a stop-plate F on its upper horizontal frame-bar d,sash-pulleys G G mounted transversely and centrally on the upperhorizontal Window-frame channel-bar B and sash-lines H passing over saidpulleys and having their ends secured to the sash D D, each strand ofthe sash-lines fitting centrally in the sashways formed by the guideribs or rails on the upright window-frame channel-bars B B,substantially as specified.
